I just bought a used RA. I want to try to dim my kessil 160we. I cracked open the relay looking for jumpers but didn't find any. The board is labeled version 8.0 is it PWM? And 0-12v? I'm guessing that I need analog?

Correct. It's the filter and you do need to have them before the amplifier.If you do the way you mentioned outside the relay box, it won't work.Not sure what you are asking about the pads.Each resistor has 2 terminals and each capacitor have two terminals.You just need to solder them on the locations shown in the board.

Ahhh I think I get it. So R1, R2, C1, C2 all have two pads. So I just need to solder the resistor terminals to the pads.

So for example the capacitor for C2 would be soldered to C2 and "+" correct?

And since you mentioned an amplifier I'm guessing I have the 12v required to dim the kessil?
